The reflector 28v has an outwardly directed annular flange 21 which abuts against the inner face of and is Secured to wall 8 by the holdfast means 25.

Secured to the inner face of the wall 1 by the holdfast means 28 is a concave reflector 29 having its reflecting surface flush with the edge portion 38 of the wall 1. The reflector 23 has an outwardly directed annular flange 3| which abuts against the inner face of and is secured to wall I by the holdfast means 28. a

The reflectors I8, 28 align. The reflectors 22, 29 align. The reflectors I3, 22, 28 and 29 are disposed in angular relation with respect to each other.

Each of the aforesaid reflectors has arranged therein on its horizontal median, as well as being secured against its reflecting surface a horizontal opaque partition 32 of a width to project from the front of the reflector to an extent to align with the leg I3 of a lens holder II which is correlated with an intermediate opening 9 in a housing wall. The partition 32, in connection with its correlated reflector and with means to be referred to, provides upper and lower chambers 33, 34 respectively'in which are arranged illuminable electric lamps 35, 38 respectively capable of being selectively made active for purposes to be referred to. The lamps 35, 38 are connected to supports 31, 33 respectively (Figure 7) arranged within the rear of the chambers 33, 34 respectively. The lamps 35, 36 are interposed in a controllable lighting circuit 39 therefor (Figure 11). The front of each of said chambers is of semi-circular contour.

Mounted in the lens holders II which correlate with the openings 9, are the annular flanges H of light transfusion lenses 42 of convexo-concavo contour which project outwardly from such holders. The holders I I, which are associated with the openings 9, coact vwith the flanges 40 for coupling the lenses 42 against the outer vertical faces of the housing I. Each of the lenses 42 have that portion of its inner face surrounded by the flange 4| formed throughout with prisms 43 ofpyramidal contour.

Mounted upon the upper face of each partition 32, at the horizontal median of the latter, is an indicator element operating shaft 44 extended from the front end 55 of the said partition. The shaft 44 passes rearwardly through an opening The opening 45 is positioned axially of the rear part of the reflector 32. The shaft 44 is retained upon the partition 32 by a strap-like retainer 48 which is secured to the upper face of the partition 32. The indicator element operated from shaft 44 is in the form of what may be termed a shadow creating arm circular portion 48 and a pointer 49 an edge part of said portion 49. The diameter of the portion 48 is greater than the width of the pointer 49. The length of the pointer 49 is Ireater than the diameter of the portion 48. The longitudinal median of the pointer 49 aligns with the axis of the portion 48. The latter. at its is is fixed to the outer end of a shaft 44. The arm 41 conforms in curvature to the inner face of a lens 42 and is disposed in close proximity to such face. The diameter of the portion 43 of the arm 41 is such that such portion will'extend above the upper face and depend from the lower 41 having a integral with face of the partition 32. With reference to Figure 8, the partition 32 is shown as provided at its horizontal median with a depressed semi-circular portion 50, and it also discloses the shape of the retainers 48. The retainer 48 has an upstanding semi-circular portion 5| which registers with the portion 58 of the partition 32 and such portions 58, 5I coact to provide a bearing for the shaft 44.

There is mounted in the holders II, which are correlated with the upper openings 5 of the vertical yvalls of the housing I, red lenses 52 of convexo-concave contour and which constitute stop" signals. There is mounted in the holders II which are correlated with the lower openings I9 in the vertical walls of the housing I, green lenses 53 of convexo-concavo contour, and which constitute go signals.

The lenses 52 and 53 are flanged in the same manner as the lenses 42 and the flanges of the lenses 52, 53 seat in the holders II which are correlated with the said upper and lower openings.

Arranged within the housing I, and correlated with each lens 52, is a controllable electric lamp I for the lamps 54, 55.

It will be stated that with respect to the lenses 52, 42 and 53 carried by each vertical housing wall, a lamp 54 is correlated with the lens 52, a lamp 35 and a lamp 38 correlated with the lens 42 and a lamp 55 lamp 54 is to completely illuminate the lens 52. The lamp 35 is to completely illuminate the upper half portion of the lens 42, the lamp 35 is to completely illuminate the lower half portion of the lens 42, and the lamp 55 is to completely illuminate the lens 53.

The apparatus includes what may be termed sets of lenses each set carried by a vertical wall portion of the housing and consisting of the lenses 52, 42 and 53. The apparatus also includes what may be termed a set of lamps or illuminating elements for the lenses of each set and such set of lamps will consist of the. lamps 54, 35, 38 and 55. A pair of the lenses 42 are aligned and the other pair of lenses 42 are aligned. A pair of the lenses 52 are aligned and the other pair of lenses pair of aligned lenses 52 are illuminated in unison.

If aligned lenses 53 are illuminated in unison. The apparatus includes a controllable lighting circuit opening and closing means constructed in a manner to provide for the illuminating of the lenses in the manner as referred to. A lighting circuit 39 is illustrated by Figure 11, for correlation with a set of lamps which illuminate a set of lenses. Each lighting circuit for correlation with a set of lamps will correspond to the lighting circuit 39 shown by Figure 11.

The controlling structure, generally indicated at 58 of the apparatus includes a prime mover in the form of an electric motor 51, a power transmission mechanism 53 operated from the motor, an intermittently operable controlling mechais correlated with the lens as. The

The said controlling structure is completely arranged in a casing 53 with the exception of part of the operating means 6| common to the shafts 44. The casing 63 is secured upon the top'wall I4 of a housing I, asindicated at 84. The controlling structure includes a supporting frame 85 for the various elements thereof, and such frame is completely housed by the casing 88. The latter is disposed in eccentric relation to the top wall I4 of the housing I.

The shaft of the motor 41 is extended and such extended portion is in the form of a socket 88 provided with a binding screw 81. The mechanism 58 includesa driven shaft 58 supported by the frame 55 and extended at one end into the socket-like extension 88 of the motor shaft. The shaft 88 is secured to the extension 88 by a screw 81. The shaft 88 is provided intermediate its end with a gear wheel 59 which meshes with a gear wheel 18 mounted on a shaft 1| iournalled in portions 12 of frame 85. Fixed to shaft 1| and disposed between the frame portions 12 and gear 18 are spacers 18. 'The shaft 1| extends from the frame portions 12 and has each end thereof provided with a crank arm 14 of. like form provided in its outer face with a dove tail groove 15. Arranged against the outer faces of the cranks 14 are adjustable couplers 18 formed with dove tail tongues 11 adjustably mounted in the rooves 15. The couplers 18 are fixedly secured in adjusted position by binding screws 18 extended through the couplers 15 and binding against the bases of the grooves 15. The screws 18 also constitute pivots for a pair of pusher members or driving pawls 19 which are disposed at a downward inclination with respect to shaft 1| and depend below the gear 18. The upper end of each member 19 is apertured. as at 88 to pro- 5 vide for the mounting thereof on the nonthreaded portion 8| of a screw 18. The adjustment of the couplers 18 is for controlling the extent of the stroke of the members 19. Each of the members 19 is provided at its lower end with a tapered 0 depending nose 82. The shaft 88' is mounted in the frame portions 88 and such portions 83 and the frame portions 12 have suitably connected therewith combined spacing and bracing means 84. l

The intermittently operable controlling mechanism 59 is driven from the members 19 and it includes a shaft85 which is common to the operating means 6| for the shafts 44 and also common to the operating means 52 for the circuit opening and closing means 88. The shaft 55 is mounted in the frame portions 88, a frame portion 88. the frame portion 88 and the frame portions 81.

Fixed to the shaft 85 is a pair of spaced parallel in the notches 98.

ranged at the other side of. disk 89 is one side of a separator member 94 of disk like form .correspending in diameter to the member 9I.- The members 9|, 94 have their outer edges align and form'in connection with the edge 98 of disk 89 an endless groove in whichthe nose 82 of a member 19 operates. The members 9|, 94 coactto prevent thenose 82 of a member 19 from shifting off of the edge 98.0f the disk 89. Positioned against the other side of themember 94 is one side of a stop disk 95 encompassing shaft'85, corresponding in diameter tothe disk 89 and having half of its outer edge 98 formed with closely arranged tapered -notches 98, spaced in a like manner as 'the'notches 92. The remaining portion of the edge 95 is uninterrupted and inset with respect to the notches 95. The disk 95 is formed with a slot99 of the sameform and arrangement as the slot 93. The slots in the disks 89, 95 are open at their outer ends and provide for removable mountingdisks 89,- 95 relative to shaft 89 and to conveniently cha'ngesaid disks when de-' sired for any suitable purpose. Positioned against the other side of disk 95 is a clamping member 91 of disk-like form corresponding in diameter to. and flush with the outer edges of the members 9|, 94. The members 94, 91coact with the outer edge of disk'95 to form an endless annular groove to confine and in which operates a stop member to be referred to. The members 9|, 94, 91 have axial openings and openings arranged adjacent said axial openings, These latter provide for mounting members 9|, 94, 91 on shaft 85. The arrangement of such openings with respect to each of said members is shown with respect to the member 94, Figure 12 and the said openings are indicated at 94*, 94', 94. The openings 94, 94 of member 91 are threaded.

Positioned against the other side of member 9| is an apertured annular flange I88 formed integral with one end of a sleeve I8| encompassing and fixed to theshaft 85 by the binding screws I82.. Carried by the flange I88 is a pair of spaced diametrically opposed hold-fast threaded means I83 which extend through the slots in the disks 89, 95 andjthe openings 94, 94 of members 9|, 94 and threadedly engage with the walls of the openings 94*, 94 of member 91 to provide for clamping said disks 89, 95 and members together whereby when an impulse is-imparted to an assembly 88 from amember 19, they will bodily move together with shaft 85. The assemblies 88 bodily move in unison with shaft 85, but such movement is had when one assembly is shifted from a member 19. There is associated with the disk 95 an adjustable stop member I84 which correlates with the notches 98 to-prevent back rotation of an assembly 88. The member I84 is formed with a nose I85 for selective engagement The member I84 is slidably mounted in and adjustable relatively to a carrier I86 therefor. The carrier I86 is pivotally connected as at I81 to an arm I88 formed on. the nam 55. The member I84 is slotted as at I89 shift the disk to the extent desired on stop (red)- or "go (green) signal. The notches will be disposed on one-half of the circumference of the disk 83; The amount of movement of the shadow hand element." is governed by. the time period disks. If it be a ten, fifteen, twenty, twenty-five or thirty seconds period, a time period disk is to be shifted, the corresponding number of equally spaced notches are arranged on half the circumference of its edge. The time period disks are so set on the shaft 85 that one shifting assembly 88 operates one-half the complete cycle of the ;stop- (red) signal and thev go,v (green) signal and the other shifting assembly operates on the other half of the complete cycle of said signals. One assembly 88 rides free of a member I8 while the other is being operated from its member 19. It is readily obvious'how in a ten seconds period the shadow hand element will move further in one interval than in; a thirty second period, so by noting .the extent of movement to the shadow hand elementthe motorist detects the length' of the period.

. There will be employedv a circuit opening and I closing means. for a pair of sets of lamps correlated with a pair of sets of signals, that is to say the sets of signals carried ,by' opposite vertical walls of the housingl, will each have correlated therewith a set-of lamps anda circuit opening and closing means will be associatedwith such sets of lamps. The circuit opening and closing means 60 will include the necessary number of normally open contact devices "I I I: eaehconsisting of a pair oflengithwiseopposed strap-like members I I2, H3 ,of conducting material provided with contactpointsilfl, H5. The men bers H2, H3 are suspended from an insulated support iI6.- The latter is-connecte d ,to the frame 85. .The members H2, H3 areconnected for. binding screw I I! for connecting the circuityvire; thereto.- The contact points 1 I I4, ,I I5 are arranged on the opposed faces of the'members H2,

H3 in proximity -to the otherends Ofthe'iatter. The members H2, H3 are: resilient and normally havethe contact pointscarriedthereby in noncontacting relation. The member. 1:13 on its outer face, and in alignment with the contact point H,5, is formedwith a nose H8, engageable' by a means, to be referred to, for shifting member H3 in a direction relativeto member H2- to provide for the engaging of the contact points I I4 and -H5 thereby closing .the lighting circuit. The shaft 85 of the mechanism 59 is arranged below the supports I I6. The members H2, H3 preferably will be formed of-bronze and the pointsI-I4 of tungsten.

The support H6 will include Bakelite sections H6 between which the members H2, H3 are arranged and project fromin opposite directions. The operatingmeans 62 of the circuit openingand controlling means comprises a series of The cams H8 are soarranged on the shaft to provide for the. cams operating their associated contact devices at the proper time. The cams H8 are so disposed whereby the higher part I 28 thereof will ride against the noses" H8 to provide for the closing of the contact devices III. The high part I20 has a tapered leading edge and an abrupt following end edge, The latter provides for sudden opening'ot-the circuit. The cams H8 preferably will be formed of Bakelite.

The operating means 8| which is common to the shafts 44 includes a bevelled pinion I2I formed on one end of the shaft 85, a bevelled pinion I22 formed on the upper end of a vertical shaft I23. which depends from the casing 63 through the opening I8 in the top wall I4 of housing I. The shaft I23 is a length to extend into a gear box I24 anchored within the housing I8 between the inner ends of the reflectors I8, 22, 28 and 28. The lower end of shaft I23 is provided with a bevelled pinion I25 which meshes with bevelled pinions I26 fixed on the inner ends of the shafts 44 which are extended into the gear box I24. As the pinion I2I meshes with the pinion I22, they will provide, when the. shaft 85; is

operated for the rotation of the shaft I23 and under such circumstances pinion I25 meshing with pinions I28 will rotate the shafts 44. The operation of the shafts I23 and 44 is an intermittent one and such operation is derived from the intermittent actuation of the shaft 85 due to the intermittent impulsing applied to the assemblies 88,- from the alternate action of the members 18. On the intermittent operation of shafts 44, the indicating elements 41 will be intermittently revolved relative to the lenses 43.

'The .motor 51" is for transmitting power to the shaft 68 to provide for the'latter totravel at 60 R. P. M. and on the operation-cf shaft 68 the assemblies. wiillbe alternately intermittently driven. .As the couplers," are adjustable, the duration of the extent of the intermittent movement imparted to the assemblies 88 may be varied. The assemblies 88 may be termed time period controlling structures and which transmit power for the purpose of operating the gears I26 witiiln-theibox I24, and such power is distributed font-ways to operate the indicating elements arr ranged relative to the four amber lenses in the intermediate their ends to the support I I8 there One end of each of said .members carries.;a;.-

[ p'iete light unit. The indicator elements may 1 ,1 '"betermedshadow hands. I

The operation of a complete unit is as follows:

I The amber lensthrough which shows'the shadow handj-is backed by the divided reflector having arranged therein the upper and lower lamps. The apparatus operates once per second hence the shadow hand does not move steady, but

The light changes are as follows: When. the indi-' cating shadow hand aligns at point A, one second beforethe change from"stop" to go" (red to green) the lower half. of the amber lens is also illuminated. At point B the stop light (red) goes off and the go light (green) on. At point C the upper half of the amber lens goes dark repeating the semi-cycle on each half of the amber lens. This operation provides the following advantages: The intermittent movement of the shadow hand element is more readily noted by the eye than a steady movement; the complete v acetate amber lens being illuminated for a period of two seconds shows the motorist at all times the position of the hand and is a positive indication when it first lights up that they have one second before stop and go lights (red and green) or go and stop lights (green andred) changes, making it unnecessary for anyone being caught in the intersections of streets leaving it open forimmediate starting of traffic in opposite directions; the number of interval movements of the shadow hand element in the upper or lower half of the amber lens indicates the number of seconds of the light period consequently the motorist's eye readily catches the remaining time left on the go light (green) period as waiting time on the stop light (red) gives him the opportunity to stop safely on the go light (green) or be prepared to move at once onthe expiration of the stop light (red) period. i

The apparatus maybe employed for fire alarm and ambulance signaling and for. this purpose the apparatus may be wired to a suitable controlling means and operated from any desired points. Where lights are operated in groups or in single units there'cambe as many as desired controlled from one or mor' points. This feature consists in blocking out all but the red lights of the traific signals in the chosen section and flashing all the red lights in this section at'the rate ofv once per second, using, of course, the red of the regular traffic signal which will be controlled by the flasher element I30, Figure 3. The switch I30 will include a cam l3l of the same form as, but of less diameter than a cam H8 and a circuit opening and closing device I32 supported from the frame 65 and controlled by the cam l3| (Figure 5). The latter iis mounted on and operated from shaft 68. s

There may be employed in connection with the apparatus a mesh? "*controlsynchronizing unit for insuring synchroni's'm of lights within its control.

The structure shown by Figure 3 is a light control unit and with slight changes may be used as a master control when connected to the aforesaid structure at a circuit opening and closing means I33 to the unit. The means I forms an element of said structure and is operated from shaft 85.

The traffic signaling apparatus or system, in accordance with this invention is so designed as to be adaptable to conversion of traflic signals now in general use to this system, which includes time indicating, fire and ambulance signals and synchronizing control.

The trailic signaling apparatus or system, in accordance with this invention is so designed to illuminate the danger with color-blind drivers of vehicles as they can be governed by the upper half of the indicator correlating with red and the lower halfofthe indicator correlating with green.

The trailic signaling apparatus or system, in accordance with. this invention provides a double protector for safety to wit:-If,'*the red or the green lightbulbburns out the upper or lower half of the amb'e jlens will control to indicate the direction of flow of traffic until the bulbs are relaced, orif the present system. a

, Preferably each of the lenses 42 will beformed of what may be termed an outer portion and an inner portion. The said portions are integral with-each other. The outer portion will be in the form of smoked glass and the inner portion of amber color. By this arrangement the shadow the'amberindicatorbulb burns out the red or green continues to direct traffic as in for and within said lover chamber provided when mm the indicator winbe at all times readily discernible through the illuminated part of the lens even though'the lens be exposed to the sun rays.
